The building at 12 Portman Square has stood as one of London's most recognisable addresses since the 1920s. Originally constructed as a private members' club for the city's merchant and aristocratic elite, its art deco bones — restored lovingly in 2014 — remain the heart of everything we do.
When the Harrington Group acquired the property in 2013, the vision was singular: to create a hotel that honoured London's traditions while meeting the expectations of the modern world traveller. Eighteen months of meticulous restoration later, HotelStaysUK opened its doors to universal acclaim.
Today, the hotel is listed in Condé Nast's Top 50 UK Hotels and holds membership in The Leading Hotels of the World organisation.
